Tiny letters in merged rtf from many eml - demoversion?

I downloaded Total Mail Converter, the Demo Version. I like most what I see, but in converting a series of EMLs to one RTF the letters are tiny. I can enlarge them, but this destroys the line arrangement. There is no possibility to chose a font and a bigness of letters for the body in the form where I guess this could be improved. - Similar in conversion to PDF, but if I type there the name of a font this font gets used, and it is in an acceptable bigness of letters. - Question: Is this a limitation of the demo version? If yes, how do I find out if the line arrangement etc. works to my satisfaction in the bought and fully registered program before I buy?

No, there are no limitations in the trial version. Please, send us an example of your eml file which you are trying to convert. Our e-mail address is support@coolutils.com. Please, add your eml file to zip or rar before sending to us.

I do here "in public" add something which I realized only when I was preparing a reproduced error files set to send. The problem doesn't arise with few EMLs to combine and convert into one single RTF, but only if I try to do it with A LOT OF EMLs (don't know from which number the problem starts, I did with 100 EMLs when it showed up).
